For the last few minutes pliny's been fairly stable with ~1gig used in
cache, a handful of free megabytes, and 600some megs of rarely used stuff
in swap (so another ~1 gig in active use in memory, about 2/3 of that
mysql). But a few minutes ago things looked a little different: over 900
megs in swap and only ~450megs used as cache. Restarting apache took 300
megs out of swap and *800 megs* out of live used memory... which promptly
filled up again over the next 30 seconds. Another apache restart seems to
have stopped this for the moment.
Bleeeh!
'vmstat 5' output below for the un-faint of heart.
